Abstract (en)

[origin: EP1724515A2] The present invention relates to a lighting device (10) with an asymmetrical distribution, of the type comprising a box-shaped body (14), on which a shield (12) is applied on one of its sides for the passage of light and inside which there is at least one light source (16), comprising, in an intermediate position between the at least one light source (16) and the shield (12), a mask (19), a portion (18) of which is open to allow the passage of light, in which the inner walls, or their portions which by reflecting the light can direct it towards the area to be excluded from the light distribution, are covered with a black antireflection element (21).
